ADA is recommending the use of a new term in diabetes management, estimated average glucose, or eAG. Health care providers can now report A1C results to patients using the same units (mg/dL or mmol/L) that patients see routinely in blood glucose measurements. The calculator and information below describe the ADAG Study that defined the relationship between A1C and eAG and how eAG can be used to help improve the discussion of glucose control with patients.
FAQs
What is the formula for converting A1C to eAG? ›
The relationship between A1C and eAG is described by the formula 28.7 X A1C – 46.7 = eAG.
What is the formula for calculating hemoglobin A1C? ›A1C(%) = (Estimated average glucose(mg/dL) +46.7) / 28.7.
What is my A1C if my glucose is 114? ›A1C test
| Result | A1C | Estimated average blood glucose level (mg/dL) |
|---|---|---|
| normal A1C level | below 5.7% | below 117 |
| prediabetes A1C level | 5.7%–6.4% | 117–137 |
| diabetes A1C level | above 6.4% | above 137 |
Random Blood Sugar Test
| Result* | A1C Test | Fasting Blood Sugar Test |

| Diabetes | 6.5% or above | 126 mg/dL or above |
| Prediabetes | 5.7 – 6.4% | 100 – 125 mg/dL |

| 6.5 | 140 | 7.8 |
| 7 | 154 | 8.6 |
It's true that carbohydrates affect your blood sugar more than other nutrients you eat. Chances are that if you overdo starchy carbs on a regular basis, your A1c number will start to creep up. But remember, all carbs aren't a problem.
Can drinking water lower A1C? ›Summary. Drinking water won't lower your blood sugar levels, but staying hydrated can help you manage them if you have diabetes. Regularly drinking enough water is healthy, and research has linked it to a reduced risk of high blood sugar and diabetes.
What is normal A1C for seniors? ›For those without other major comorbidities, an A1C goal of 7–7.5% and a fasting glucose target range of 6.5–7.5 mmol/L (117–135 mg/dL) are recommended, whereas for frail older adults and those with multisystem disease, an A1C goal of 7.6–8.5% and a fasting glucose target range of 7.6–9.0 mmol/L (137–162 mg/dL) are ...
What A1C is no longer diabetic? ›The American Diabetes Association (ADA) released guidelines last month defining "remission" as an A1c < 6.5% "measured at least 3 months after cessation of glucose-lowering pharmacotherapy." They further recommend that: A1c testing occur at least annually to confirm continued remission.
Should I be worried if my glucose is 114? ›
A normal fasting blood sugar level is below 100; whereas, the level of a person with prediabetes is between 100 and 126. Once levels have surpassed 126, it's classified as Type 2 diabetes.
Should I worry about fasting glucose 114? ›Fasting blood sugar test
In general: Less than 100 mg/dL (5.6 mmol/L ) is normal. 100 to 125 mg/dL (5.6 to 6.9 mmol/L ) is diagnosed as prediabetes. 126 mg/dL (7.0 mmol/L ) or higher on two separate tests is diagnosed as diabetes.
A1c Levels
For people without diabetes, the normal range for the hemoglobin A1c level is between 4% and 5.6%. Hemoglobin A1c levels in the range of 5.7%-6.4% mean you have prediabetes and a higher chance of getting diabetes. Levels of 6.5% or higher mean you have diabetes.
If you have good control over diabetes then the good news is that HBA1C can drop by 10%.
What is a normal eAG level? ›The normal value for eAG is between 70 mg/dl and 126 mg/dl (A1C: 4% to 6%). A person with diabetes should aim for an eAG less than 154 mg/dl (A1C < 7%) to lower the risk for diabetes complications.
How to translate the A1C assay into estimated average glucose value? ›Calculated AGmg/dl=28.7 × A1C − 46.7 (AGmmol=1.59 × A1C − 2.59) (R2=0.84, P < 0.0001). The translation of A1C to estimated AG (eAG) based on the linear regression is shown in Table 2, for conventional and SI units, and with the 95% prediction limits.
What is my A1C if my average blood sugar is 126? ›A1C and self-monitoring
| A1C level | Estimated average blood sugar (glucose) level |
|---|---|
| 6% | 126 mg/dL (7 mmol/L) |
| 7% | 154 mg/dL (8.6 mmol/L) |
| 8% | 183 mg/dL (10.2 mmol/L) |
| 9% | 212 mg/dL (11.8 mmol/L) |

An A1C of 6.5% or higher indicates diabetes. Dangerous levels of A1C are 9% and higher. An A1C above 9% increases the risk of long-term diabetes complications like blindness, nerve damage, and kidney failure. 1 Under 7% is considered good diabetes control.
What is a HGB A1C with eAG estimation test? ›The hemoglobin A1C with eAG test is typically ordered when someone is monitoring their ability to control their blood sugar. Your doctor may recommend having the Hemoglobin A1C test two to four times per year to monitor treatment.
